Thyroid and symptoms
Hi new here and need some advice if possible I went through break up in 2007 by 2008 I had dropped from a size 16 to an 8 I was diagnosed then with irritable bowel depression/anxiety due to me feeling freezing all the time like I'm just about to go down with flu or something - I cannot gain weight I have just undergone total hysto including ovaries at 36 due to pcos (heavy irregular bleeding constant infections etc..) I am having night sweats also for the last nearly 8 years there has been no change to this after hysto and I'm on hrt 75mcg with no change at all I have spells of chest pain dizzy ness breathlessness and headaches more recently I have been having severe memory problems I'm a mum to 3 and it's causing problems - i had a stillbirth 29 weeks 3 yrs ago tsh was not quite right but in normal limits.
Every blood test I have had with thyroid function the last 18 months has been not quite right as the dr (different ones each time) has put it (in uk same surgery) I had a private thyroid function test done 6 months ago showing tsh at 0.17 will try to upload comments here.
This week my dr has called the latest round of blood tests has shown something not telling me what til I go with my thyroid.
The thing is I seem to get so close to them figuring this out then they send me home with the same generalised anxiety disorder they relabelled me with after my daughters still birth - yes I was anxious being pregnant again afterwards and yes I keep feeling panicky but I'm happily married not depressed and run a successful business whilst being mum - what do I do when I see the dr any advice
After my op my temp sat at 35 they couldn't raise it bought me blankets
My blood pressure has been low since all this started also
Thanks in advance for reading I may have missed some symptoms as my brain is slow these days :) thanks x
